Hello, have a problem, two may not be related. Recently did the timing belt/water pump. Put it all back together. And now am blessed with missfire scan codes and indeed, engine does miss.
has new Iridium plugs wires, distrib cap, rotor. Ran fine before change. Checked Timing belt timing. All spot on. TE-1 E-1 underhood connector with timing light. I did notice that in this test mode, the car ran great!! I read that the computer is using programmed values instead of sensor data in this mode. I got a scan tool and this is one round of scan with this unit. maybe someone here is familiar and could offer a possible culprit.
